ESM loading fails in the browser

[KeithHenry]

Loading the module fails in the browser:

This fails because it attempts to fetch("markdown.wasm") which (because it's ESM loaded) gets resolved on the root path, not the path relative to the module.

So import * as markdown from "../{library}/markdown-wasm/dist/markdown.es.js"; should fetch("../{library}/markdown-wasm/dist/markdown.wasm")

It should use import.meta.url to resolve to the same path.
